肘关节角度与外负荷的关系

On the Relation between Elbow Joint and External Load

肘关节在做屈伸运动时 ,关节角度与肌力之间存在一个最佳的发力位置。当角度为 90°～ 1 0 0°时 ,肌力的运动效果最佳 ,克服的阻力最大。这个最佳角度与阻力的方向无关。

There is an optimal angle while the elbow joint exercises.The value of this optimal angle is between 90° and 100°.In this position,the effect of muscle force is the strongest and may take over more load.The direction of load has no effect on the optimal angle.
